What to Know About Motor Oil Viscosity

A motor oil's viscosity is a measure of how fast it moves. Generally speaking you want oil with a higher viscosity when the engine is warm. This is because oil will get thinner as it heats up. Therefore, it needs a higher initial viscosity to ensure proper coverage of engine parts.

Conversely, you want a lower viscosity oil when the engine is cold because it will flow fast enough to avoid becoming too thick. On a bottle of motor oil, the first number that you see is the viscosity when the engine is cold. The second number is the viscosity of the bottle when the engine is warm.
